Tata Docomo is really decent is the services and tarrif. I havent faced any fraudulent deductions from my account, since I got the connection. The only drawback about the company is, the call quality. The voice is not crystal clear and in some areas the coverage is poor.
If the company improves the signal quality, it will be best provider in the country.
Customer support: 9.5/10
Call quality and Internet speed: 5/10.
Tarrif: 8/10.
